The new mineral plavnoite (IMA2015-059), ideally K0.8Mn0.6[(UO2)2O2(SO4)]•3.5H2O, is a member of the zippeite group. It was found in the Plavno mine, in the eastern part of the Jáchymov ore district, Western Bohemia, Czech Republic, where it occurs as a supergene alteration phase formed by hydration–oxidation weathering of uraninite in hydrothermal U-veins. It was found to be associated with marécottite, magnesiozippeite, blatonite and gypsum. The mineral is named after the type locality - the Plavno mine. In this work the mineral's properties and crystal structure were studied and the resul ts are presented.
